MASONRY CORNER GUID'E.

Application filed May 13, 1922. Serial No. 560,641.

of Michigan, have invented new and useful Improvements in Masonry CornerGuides, of which the following is a specification.

The object of my said invention is the provision of a simple and easilyapplied device for useto advantage in the laying of Corners in masonrywork, this with a view to saving labor and assuring accurate productionof a corner.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specificationz-Figure 1 is a perspective showing my novel corner guide in use.

Figure .2 is a horizontal section taken through the device in a planeabove the spring and also showing the device as applied.

Similar nuinerals of reference designate corresponding parts in bothviews of the drawings. w

Among other elements my novel device comprises an upright angle memberor angle iron 1, i. e., a. member of right angle form in horizontalsection as definitely appears in Figure 2. On the face of one or both ofits portions the said member 1 is provided with graduations 2, spacedapart according to the height of bricks to be incorporated in a wall.Riveted or otherwise appropriately fixe'd to the upper end of the member1 are plates 3, disposed at right angles to each other and each equippedwith a horizontally disposed spirit level or plumb glass 4.

The 'said member 1 is designed to be held against downward movementthrough the medium of a pin 5 disposed immediately under the member 1and disposed in a mortar portion of a wall.

n association with the member 1 I employ a retractile spring 6 which isrelatively arranged as shown and is designed to be maintained inposition through the medium of pins 7, the said pins 7 being (preferablywedge-shapcd and designed to be riven into Vertical joints of two wallportions at right angles to each other. Manifestly when the spring 6 isrelatively arranged as shown and described the said spring will straddlethe member 1 and thereby hold the member 1 yieldingly to its work andagainst casual lateral movement in any direction. The

plumb glasses or spirit levels ll have for their function to keep themember 1 plumb each way and to obviate the necessity of handling amasons level in laying up the corner. In the event of the member 1 beingaccidentally moved or displaced, the spring 6 will cause the member 1 tospring back to working position, and in this connectio-n it will benoticed in virtue of my improvement it is unnecessary to do any nailingas would be the case if a common straight edge was employed.

Incident to the use of my improvement, the guide member 1 serves torender plumbing unnecessary until the wall is laid to the height of thesaid member 1; T'Vhen the wall 'extends to the top of the member 1, the

spring 6 is fastened in the manner described in Vertical joints adjacentto the top of the wall, and the member 1 is raised within the spring tothe height desired. I would also have it understood that after the wallhas been laid to the proper height for the attachment of the member 1,the brick can then be laid to any desired graduation 2, it beingunderstood in this connection that the said graduations 2 indicate theheight of the several courses of brick. From this it follows that fromthe use of my novel device, the necessity of laying up a lead at thecorner to line the work by it is obviated.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order Ato impart a full, clear and eXactunderstanding of the said embodiment. I donot desire, however, to beunderstood as confining myself to the said specific construction andrelative arrangement of parts inasmuch as in the future practice of theinvention various changes and modifications may be made such as fallwithin the scope of my invention as defined in my appended claim.

Having described my invention, what I clam and desre tO secure byLetters Patenty is A masonl'y corner guide comprsing an upl'ght :mglemember edapted 'to be supported in straddling relation to the cornell ofa wall and provided at its nppel` end With plnmbng means, a l'etraetilespring strad- FRANK 7.
